30 minuets for 20 mph because 10m/h /2
<span>Answer: 5.32 x 10⁻³ M
Explanation:
1) The rate law for a first order reaction is:
</span><span />
<span>r = - d [A] / dt = k[A]
</span><span />
<span>2) When you integrate you get:
</span><span />
<span> [ A] = Ao x e ^(-kt)
</span><span />
Remember that here A is PH₃
<span>3) Plug in the data: Ao = 0.0316M, k = 0.0180 /s, and t = 99s
</span><span />
<span>[PH₃] = 0.0316 M x e ^( - 0.0180/s x 99s) = 5.32 x 10⁻³ M</span>
Answer:
Only anions
Explanation:
Polyatomic positive ions often have common name ending with the suffix anions
True because usually when you add stufff to a solution it increases
